<P>PROBLEM TO BE SOLVED: To perform the cutting of an inner surface of a pipe with a relatively small diameter. <P>SOLUTION: A cutting apparatus includes: a rotation mechanism 3 for rotating a cutter 2 disposed in the pipe 101e; a circling mechanism for circling the cutter 2 around a predetermined axis S1; an axial movement mechanism for moving the cutter 2 along an extending direction of the axis S1; and a crossing direction movement mechanism 6 for moving the cutter 2 in a direction crossing the axis S1. The crossing direction movement mechanism 6 includes: a cutter supporting part 11A for slidably supporting the cutter 2 in a direction crossing the axis S1; a sliding part 63 provided so as to be slidably movable in the extending direction of the axis S1 relative to the cutter supporting part 11A; and a cutter moving part 64 provided at the sliding part 63 while being coupled to the cutter 2 and oscillating the cutter 2 accompanied by the slide movement of the sliding part 63 to move a cutting blade in the direction crossing the axis S1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
